Code to apply indicator (symbol change) on all charts

[bosslife]

i need help <3 i found this indicator, a symbols dashboard. i want it to change the symbol on all open charts so i added "#include  <Charts\Chart.mqh>;" but it doesnt work. do i need to ad more codes or am i on the wrong path? can't find a similar script in the codebase :(

#property indicator_chart_window
#property indicator_buffers 0
#property strict
#include  <Charts\Chart.mqh>;         // that's what i added to change the symbol on all charts


extern string  UniqueID      = "SymbolChanger1"; // Indicator unique ID
extern int     ButtonsInARow = 9;                // Buttons in a horizontal row
extern int     XShift        = 20;               // Horizontal shift
extern int     YShift        = 20;               // Vertical shift
extern int     XSize         = 66;               // Width of buttons
extern int     YSize         = 21;               // Height of buttons
extern int     FSize         = 10;               // Fort size
extern color   Pcolor        = clrGainsboro;     // Back pannel color
extern color   Bcolor        = clrSilver;        // Button color
extern color   Dcolor        = clrBlack;         // Button border color
extern color   Tncolor       = clrBlack;         // Text color - normal
extern color   Sncolor       = clrRed;           // Text color - selected
